The acceleration of a knife dropping is still 9.80 m/s2 but we say it 10m/s2 just for simplicity but the actual value of acceleration due to gravity is 9.8m/s2 ( We write 10m/s2 in calculation to avoid complex calculation)
The acceleration due to gravity is maximum at surface of earth on going high attitude the value of acceleration due to gravity decreases but it doesn't increase. To increase or decrease the acceleration ( Speed up or Down) of the knife we have to apply external force.
I hope you got my point if have any more doubt comment below
The found acceleration of a knife dropping into peanut butter was 10 m/s^2. Does it make...
The acceleration of gravity is found by dropping a ball from various heights. The data for the experiment is as follows: Distance, d (meters): 15.43 17.37 19.62 21.68 Time, t (seconds): 1.804 1.915 2.043 2.149 a.) Copy these data and add a third row which contains the calculated accelerations due to gravity as given by g = 2d/t^2. b.) By finding the mean and standard deviation, show that the answer is inconsistent with the accepted value of g = 9.80...
A potato is thrown straight upwards with a speed of 10 m/s. How long does it take to reach a height 2.2m above where it started while descending (on the way down)? Neglect air resistance, and assume the acceleration due to gravity is g=-9.8 m/s^2.
The acceleration of gravity is 9.8 m/s 2 . To emphasize the fact
that lessons learned in 303K carry over into real life, this
problem is based on an accident report from the Worker’s
Compensation Board in Bryant, Texas. Dear Sir/Madam: I am writing
in response to your request for a fuller explanation on the cause
of my accident. I trust the following details will be sufficient.
On the day of the accident, I was working alone laying bricks on...
An object moving in the *x direction experience an acceleration of *2.0 m/s^2- This mean the object is increasing its velocity by 2.0 m/s every second. travels 2.0 m In every second. is traveling at 2.0 m/s. is decreasing its velocity by 2.0 m/s every second. Suppose that an object is moving with a constant velocity. Which statement concerning Its acceleration must be correct? The acceleration is constantly increasing. The acceleration is a constant non-zero value. The acceleration is constantly...
1). Near the earth surface, acceleration due to gravity is 9.8 m/s a) True b) False c) Can's say 2). The force exerted normal to the surface is called "normal force" a) False b) True c) Statement is wrong 3). The normal force Fn acting on a horizontally place object of mass 10 kg is (assume at rest) a) 98 N b) 90 N c) 49 N d) 50 N 4). An object of mass 'm' is accelerated vertically upward...
Version 1 0.) Red light propagates through window glass at a speed of 2.0 x 10 m/s. This means that bli light must propagate through vacuum at a speed of: A) 1.5 x 10 m/s B) 2.0 x 10 m/s C) 2.5 x 10 m/s D) 3.0 x 10 m/s E) No way to know with the information given, but it must be <3.0 x 10 m/s A screen red, yellow, blue glass 7.)

Question 6 It is required to construct a 4 m deep underground carpark in the heart of the city of Melbourne without disturbing the surrounding area. The required excavation for the proposed carpark and also the adjacent ground condition are shown in Figure 6.1. As can be seen from the figure, the adjacent ground consists of a 2 m deep clay deposit, resting on a 2 m thick sand deposit, where stable soil could be found below the sand deposit...
